The invention belongs to the technical field of deformable wings, and particularly relates to a variable-camber wing trailing edge auxiliary driving mechanism which is a driving mechanism for assisting a main driving mechanism to complete follow-up of a variable-camber wing trailing edge skin. The invention provides a variable-camber wing trailing edge auxiliary driving system. The variable-camber wing trailing edge auxiliary driving system comprises a trailing edge cabin beam, a support, a main driving shaft, a first connecting rod, a second connecting rod, a third connecting rod, a stay wire, several groups of springs and several fisheye gaskets. Aiming at a high-efficiency knuckle-type connecting rod driving variable-camber wing trailing edge scheme, a main mechanism has insufficient control and support capability on deformation of the tail end of the variable-camber wing trailing edge, and particularly when an aerodynamic load is borne, the deformation of the tail end of the trailing edge is not coordinated with the deformation of the whole wing trailing edge, so that the wing trailing edge is not smooth in deformation, and the aerodynamic performance of the wing is seriously influenced. In order to solve the problem, a group of trailing edge auxiliary driving mechanisms are designed, and the deformation of the tail end of the trailing edge is accurately controlled through follow-up control on the skin.
本发明属于可变形机翼技术领域,具体涉及一种变弯度机翼后缘辅助驱动机构,辅助主驱动机构完成变弯度机翼后缘蒙皮随动的驱动机构。本发明提供一种变弯度机翼后缘辅助驱动系统,包括:后缘舱梁、支座、主驱动轴、第一连杆、第二连杆、第三连杆、一根拉线、几组弹簧、几只鱼眼垫圈。针对高效率“指节式”连杆驱动变弯度机翼后缘方案,主机构对变弯度机翼后缘尾端变形控制和支持能力不足,尤其是承受气动载荷时,后缘尾端变形与整个机翼后缘变形不协调,造成机翼后缘变形不光顺,严重影响机翼气动性能。为了解决该问题,本发明设计了一组后缘辅助驱动机构,通过对蒙皮的随动控制达到对后缘尾端变形的精准控制。
